` SPECIFICATION forming pm of Letters Patent 110.402,20?, dated April so, 1889.

Application iled January 14:, 1889 Serial No. 296,281. (Model.)

To all whom it may concern:

Be it known that we, HERMAN TRIPP and LOUIS LATTAN, citizens of the United States, and residents 0E Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in'HaspiLocks, of which the following isa specification, reference being had to the accompanying drawings, illustrating the invention, in which-n Figure l is aplan of the blank of which the hasp and lock-case is formed. Fig. 2 is a perspective representation of the hasp-lock com.- plete for use; Fig. 3, a plan of the lock and its supportingplate removed from the case; Fig. 4, a top View of the hasp and lock in position on a door or gate, with one edge of the case removed to show the lock inside of the case; Fig. 5, an elevation ofthe key-post, and a broken section of the lock-plate and case;

Fig. 6, an elevation of the catch removed,

from the other parts. I

The purpose of this invention is to provide a hasp and lock which shall be light, strong, and be free 'from interference of ice. To accomplish this, we construct the hasp and lockcase of a single piece of metal cut by dies in the proper shape to be-formed by dies, so that the projection of the lock-case shall be wholly on one side ot the hasp portion, and a supporting lock-plate which lies within the case and on the hasp-plate, and held to that plate by the keypost. A slot is formed through the hasp-plate at the back of the lockcase to permit the catch to pass through and engage the-latches of the lock, whereby nov water can enter the case andfreeze, to interfere with the working of the lock. y,

G A B C C D represent a blank, which is preferably cut from soft v sheetfsteel to form the hasp and lock case. A is the haspplate. B forms the front or face side of the lock-case; C C, the side edges; G, the outer end; D, the inner end; and that portion of the hasp-plate between dotted lines c and r 'forms the back of the case.

The lines e c h d g show where the blank is to be bent at right angles to form the hasp and lock-case. (Shown at Fig. 2.)

Before the blank at Fig. 1 is bent a catclvslot, E, a key-slot, a, and a post-hole, P, are formed through it, and mortises h h are also made through it to receive tenons ff on the edge of vfrom the plate L.

the inner end portion. A hole, F, is also punched through the hasp-plate, as is the cusi tom, to receive a staple, H, which holds the hasp toa door or gate.

L represents the plate which supports the lock, and it is formed with an area corresponding to that of the inside of the case, so that the plate shall havey no lateral movement. The lock-plate is held to hasp A, forming the back of the case, by the key-post e', which is formed with a shoulder, j, and a tenon, Z, on its lower portion, which passes through the lockplate L and hasp-plate A, and is headed down.

The plate L is to be placed on the plate A before the front oi' the lock-case is fully brought to the position shown at Fig. 2, and when said case is in about the position indi# cated by dotted lines w, afterwhich the tenons ff are headed, as is also the tenon Z of the key-post 'L'.

The. latches of the lock are shown at M M, and are pivoted to the plate L at n n, and their free ends are prevented from coming too closely together by means of a nib, S, cut and turned up from the said plate L. The latches M are held under the catch K by ordinary springs, V, supported by nibs R R, turned up The catch K is rounded on its outer portion, so that when the latches M M are shut on it they will spread apart and come into the notches below as the case is pushed to the post or dooiej amb. (Shown at J, Fig. 4.)

The key inserted on the post t' and turned one-quarter round will force the latches M M out from the catch K, as shown by dotted lines a' w, said dotted lines showing also the position of the catches when forced apart preparatory to engaging the notches in the catch K.

The catch K may be secured by any'ordinary mean s-such as screws, wrought-nails, or bolts-and the end of the hasp may be removably secured by a hook, Il, to a door or gate, a portion of the top of which is shown at I.

The lock shown is of the simpler form; but any of the betterstyles of locks, so far as proof against picking is concerned, may be attached to the plate L. The forms of the latches and the catch, however, are preferable.

Too

Having thus described our invention, what 1. In combined hasps and locks, the hasp and lock-case formed of a single piece of metal, as shown, the saine being bent at right angies on the lines l) c to form the outer end, G, of the lock-case, bent on the line e to form the inner end, D, of the salne, and bent on lines d g for the parts C to forni the edges of the case, the portion B forming the front and the hasp portion A forming; the back thereof, and the inner end portion, D, provided with tenons f f, which engage niortises in the hasp portion, the back of the case provided with a slot for the passage of the catch, and the face of the case provided with a key-sot in coinbination With a lock the supporting-plate of which is secured to the back of the case by the key-post 1'-, and a catch projecting through the back of the case, as specified.
